Some bialgebroids constructed by Kadison and Connes-Moscovici are isomorphic
Florin Panaite, Freddy Van Oystaeyen
We prove that a certain bialgebroid introduced recently by Kadison is isomorphic to a bialgebroid introduced earlier by Connes and Moscovici. At the level of total algebras, the is…
A structure theorem for quasi-Hopf comodule algebras
Florin Panaite, Freddy Van Oystaeyen
If H is a quasi-Hopf algebra and B is a right H-comodule algebra such that there exists v:H\to B a morphism of right H-comodule algebras, we prove that there exists a left H-module…
Note on The Cohomology of Color Hopf and Lie Algebras
Xiao-Wu Chen, Toukaiddine Petit, Freddy Van Oystaeyen
Let be a -Hopf algebra with bijection antipode and let be a -graded -bimodule. We prove that there exists an isomorphism \mathrm{HH}^*_{\rm gr}(A, M)\cong{\rm…
L-R-smash product for (quasi) Hopf algebras
Florin Panaite, Freddy Van Oystaeyen
We introduce a more general version of the so-called L-R-smash product and study its relations with other kinds of crossed products (two-sided smash and crossed product and diagona…
Good Reduction of Good Filtrations at Places
Toukaiddine Petit, Freddy Van Oystaeyen
We consider filtered or graded algebras over a field . Assume that there is a discrete valuation of with its maximal ideal and its residue fie…
The equivariant Brauer group of a group
S. Caenepeel, F. Van Oystaeyen, Y. H. Zhang
We consider the Brauer group of a group (finite or infinite) over a commutative ring with identity. A split exact sequence $$1\longrightarrow {\rm Br}'(k)\…
